NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with a scan tool.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.

Audible Warnings
The body control module (BCM) will provide an audible warning for various events relating to the vehicle. The functions that provide an audible warning are the key in ignition, the lights on, the occupant restraint (seat belt) and the park brake.
Key in the Ignition Audible Chime
The BCM will provide an audible chime if the key is left in the ignition in either OFF or the accessory position with the driver's door open. The chime rate for this is 150 chimes per minute. The key in the ignition chime has a higher priority than the lights on chime.
Lights on Audible Chime
The BCM will provide an audible chime if the park lights are on and the driver's door is open. In addition, 1 or 2 other conditions exist. The key is out of the ignition, or the key is in the ignition in the OFF position, and has not been turned. The BCM will chime at a rate of 200 chimes per minute until the conditions are removed.
Occupant Restraint Audible Chime
The BCM will provide an audible chime based on the class II message received from the SDM if the driver's seat belt is not buckled when the ignition is turned to run or crank. The chime rate for this feature is 50 chimes per minute.
Park Brake Audible Chime
The BCM will provide an audible chime for park brake when the park brake is applied and the vehicle speed is higher that 3 mph. The chime rate for this feature is 200 chimes per minute.

You can't disconnect anything . The problem has to be fixed .

The BCM will provide an audible chime for park brake when the park brake is applied and the vehicle speed is higher that 3 mph. The chime rate for this feature is 200 chimes per minute.

Telltale Chimes
The body control module (BCM) will provide 4 chimes for each telltale activation per ignition cycle, at a rate of 150 or 200 chimes per minute. The chimes are limited to 1 chime event per telltale for each ignition cycle. The power up telltale function will not activate the telltale chime function. If the telltale becomes active during a cycle then the chime will sound.
The following telltales will activate the chime function:
• Low Washer Fluid
• Change Oil Soon Indicator
• Brake Fluid Low
• Oil Pressure Low
• Coolant Temperature Hot
• Low Coolant Level
• Low Fuel Level
• Antilock Brake System
• Volts Light (Generator)
• Supplemental Inflatable Restraint System (Air Bag)
• Trunk or Hatch Ajar

Having the vehicle checked for DTC'S - diagnostic trouble code's in the BCM would be the first step in the diagnostic procedure .
DTC B2965
When the ignition key is seated in the ignition switch, the key-in-ignition switch contacts the close, grounding circuit 80. The body control module (BCM) monitors the state of the key-in-ignition switch, the state of the ignition switch (OFF, ACC, or RUN) and the driver's door to control the key-in-ignition chime.

The chime is active because the sensor on one of the doors keeps reporting it as open - this is a defect in the sensor, located inside the actual lock. You cannot disable the chime, it's an integral part of the Body Control Module. To fix that the door will have to be dismantled and the sensor replaced, a job for a repair shop.
Until you reach one you can disconnect the battery and lock the doors manually.

It is normal operation for the odometer to light up with the driver's door being opened. It is not normal for the chime to go off. The "Key-In Switch" in your steering column is malfunctioning. The body control computer "Thinks" the key is in the ignition when it is not. It usually requires a new key tumbler assembly to fix this.

Sometimes the ignition key does not "deactivate" when removing the key...try wiggling the washer behind where the key goes...sometimes this sticks...:)

Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
